【摘要】 智能多路数据采集系统实现了多路温度采集与检测 ,利用仪用放大器AD6 2 0进行信号放大 ,采用LM331型电压 -频率转换器进行电量转换 ,采用 89S5 2单片机进行数据采集及存储并用VisualBasic 6 0实现单片机与PC机的通信 ;最后给出了智能多路数据采集系统在梅江小区综合办公楼生态能源示范系统的应用数据更多还原

【Abstract】 This system can collect and check temperatures.It uses AD620 amplifier to magnify signals, LM331 voltage-frequency transformer to transform electricity quantity in the A/D transforming part, and 80C51 chip to collect and store data to communicate with PC by using Visual Basic6.0 language. This paper also offers the data from the MeiJiang District to which the system is applied.[更多还原
